After finishing antibiotic, My ear still hurts( I did diagnosis pneumonia)

I got diagnosis walking pneumonia this week and on the antibiotic for 7days. tomorrow will be the my last day of the antibiotic.
cough, throat got feel better but my ear still really hurts!!! can’t lay down side of my ear and can’t even sleep at all. night get more worst. so i went to ENT doctor and he told me that i do not have ear infection,but “It might be TMJ disorder, ear pain is nothing to do with your pneumonia. Teeth grinding,gum chewing,or dental problem.” but i do not grinding my teeth,chewing tough food or chewing much. recently, I went to dentist.
if anyone has any idea for this matter?? I am so much pain and so annoying!! please help me!!
